I've never played the demo, but I really can't stand MPH. The controls are so awkward that you end up giving yourself carpal tunnel syndrome and there are many areas that look the same.
I never played the demo, but MPH is actually a good game for the DS. If you haven't played it, try it out if you like FPS type of games.
As for all the areas looking the same, all the planets look very very different. However once you're on the planet all the textures are the same, but it's not as if other metroid games don't do that already.
There was no metroid at all in final Metroid Prime Hunters, but there WAS metroid in Metroid Prime Hunters: First Hunts. I played the demo since when I first had a ds.
Metroids were in the demo, kewl Final game: no metroids, sucky The demo had a cool remix of ridley's theme Final game: no ridley's theme remix. The demo was much more amusing than the final product, from which I only really enjoyed the remix of the boss battle with metroid prime(used in Gorea 2)
The single was a crap full of bland planets, followed by bland OST, followed by bland story. And the multiplayer was crowded with cheaters. IMO, the worst metroid ever
I guess I must've played the multiplayer before the cheating thing got big. The only time I ever remember finding a cheater was when you could use that one guy who turns into a turret and jump into the wall and easily kill people.
I do remember after my friend got an action replay, we wondered if you could use it on MPH on wifi. We never did try it, but I doubt Nintendo had any anti-cheat things in place to stop it.
it actually has my favorite ost of the entire series. it's very different but it's different in a good way. i still listen to it all the time and i can't say that for the others.
